The question is... suppose it requires 100 dynes to change the length of a certain spring 5 cm. What force is required to change the length of the spring 20 cm?

Would you just multiply it... and say it would take 400 dynes?

Sounds good to me :smile: Springs are linear. If you wanted to be more formal about it, you could find the spring constant k from Fspring=k*x since you know Fspring and you know x.
